Hi,
I am trying to build a function and from a script but it does not seem to be working. Can anyone see anything wrong with this?
Also i need it to convert the large image to a specific size also, like the thumbnail so i need to put something in there so i can enter a width of the large image and this will be resized also.
Here is the function:
[PHP]function uploadimage($value){
$path_thumbs = "uploads/thumbs";
$path_big = "uploads/big";
//the new width of the resized image.
$img_thumb_width = 150; // in pixcel
$extlimit = "yes"; //Do you want to limit the extensions of files uploaded (yes/no)
//allowed Extensions
$limitedext = array(".gif",".jpg",".png",".jpeg",".bmp");
$file_type = $_FILES['image']['type'];
$file_name = $_FILES['image']['name'];
$file_size = $_FILES['image']['size'];
$file_tmp = $_FILES['image']['tmp_name'];
//check file extension
$ext = strrchr($file_name,'.');
$ext = strtolower($ext);
if (($extlimit == "yes") && (!in_array($ext,$limitedext))) {
echo "Wrong file extension. <br>--<a href=\"$_SERVER[PHP_SELF]\">back</a>";
exit();
}
//get the file extension.
$getExt = explode ('.', $file_name);
$file_ext = $getExt[count($getExt)-1];
//create a random file name
$rand_name = md5(time());
$rand_name= rand(0,999999999);
//get the new width variable.
$ThumbWidth = $img_thumb_width;
//keep image type
if($file_size){
if($file_type == "image/pjpeg" || $file_type == "image/jpeg"){
$new_img = imagecreatefromjpeg($file_tmp);
}elseif($file_type == "image/x-png" || $file_type == "image/png"){
$new_img = imagecreatefrompng($file_tmp);
}elseif($file_type == "image/gif"){
$new_img = imagecreatefromgif($file_tmp);
}
//list width and height and keep height ratio.
list($width, $height) = getimagesize($file_tmp);
$imgratio=$width/$height;
if ($imgratio>1){
$newwidth = $ThumbWidth;
$newheight = $ThumbWidth/$imgratio;
}else{
$newheight = $ThumbWidth;
$newwidth = $ThumbWidth*$imgratio;
}
imagecopyresized($resized_img, $new_img, 0, 0, 0, 0, $newwidth, $newheight, $width, $height);
//save image
ImageJpeg ($resized_img,"$path_thumbs/$rand_name.$file_ext");
ImageDestroy ($resized_img);
ImageDestroy ($new_img);
//upload the big image
move_uploaded_file ($file_tmp, "$path_big/$rand_name.$file_ext");
}
$value = "$rand_name.$file_ext";
return $value;
}[/PHP]
Thanks in advanced.
